,To all 'wkom 'it may concern," Beit known that'I, HENRY M. SHEER,

citizen of the United States,

of Illinois, have invented certain new and useful Improvements in OilControls for Burners, of which the following is a speci- My presentinvention relates to an improvement in oil controls for burners.

The present invention comprises a tandem oat for automaticallycontrolling the flow of oil in oilfburning heaters. The object of thetandem float is to maintain at all times an exact oil levelat theproper' place,-1e

' tion the'heater is tilted. The point where tion theexact oil levelmust be maintained is,

of course, the burner. If the oil variesI at. the burner, vor if the oilpressure varies .at

1the valve that. controls the oil to the burner,

the llame will vary accordingly. For this reason, and to accomplish theresults desired, the float' control valve preferably should be locateddirectly beneath the burner, and the needle valve controllingthe -flowof oil to the burnerprefe'rably'should be directly below the burner.'The best U known way iny which the foregoing assemblyv can be securedis to employ two floats in v tandem, pivotally connected with andsupportin a -connecting bar, lto which bar a valve 1s connected' whichis operatedby both floats throughthe medium of the connectinghar. Y l Inthe accompanying drawingszh- Fi 1 -is'a vlewfinfelevation witha-porroken away; Fig 2 is a 'vertical section on the-line 2-2of-Fig.1;v

Fig.- 3 i's a similar view vshowing the device as applied.; and] Fig.4`is .a perspective view of the'float j connecting bar.

The ou. chamber prefrablyeonsists ef two parts 1 and 2, preferably ofcast metal having flanges aroundltheir edges land held togetherv byscrews or bolts 3, with'a su1table acking or gasket (not shown). betweenThe numeral- 4 represents `two oil cups having the floats 5 therein.These iloats are adjustably and `'removably connected with rods or wires6, and the latter are pivotally v`r.connected at theirv lower'ends'wniththe cona. residing atin the county of Adams and State' tank tothe center sequently 4necting bar 7, which latter suspended or sustained.by the floats. The chamber formed in the parts 1 and 2 communicateswith the cup's 4,' and forms a float chamber which extends'i'nto both ofthe cups 4 insurmg that the oil levels in both of these cups are in thesame horizontal lane.

` A ball-valve 8 is secured on the ower end of a rod or wire 9 pivotallysuspended from the connected bar at the point 1 0. The ball 8 ispreferably made of bronze or brass and machined or ground perfectlytrue. A hole is'drilled through the ball, the size ofthe wire 9, and thelatter extended through the ball a short distance and the ball issoldered at this pointpains being taken tov prevenu thesolderfiomgettingon that part of the ball which serves yas a valve. The numeral 11represents the valve-seat.

B, represents the burner, and the numeral 12 is the usual needle-valveoperating in the valve chamber 13. T, is the oil tank, and the numerals14L and 14 'represent elbows for connecting the pipes 15 leading fromthe of the oil chamber, as

shown in Fi 1.

In assexribhng the parts, the burner B and needle-valve 12 are firstscrewed into the upper part of the oil chamber, as shown at' the threads16, and the oil cups 4 are simlarlyassembled at the outer ends of theoil chamber. The floats 5 with wires 6 attached are next laced in theoil cups, the wires extending s chamber where they are pivotallyconnected to the opposite ends ofthe connecting bar ally connected tothe this wire is -then inser'ted through the sleeve in the lower part ofthe oil chamber, and the. two oil-chamber own through. into the oil- 7.The wlre 9 for the ball-valve 8 is pivotv parts 1 yand 2 c-an now beboltedftogether. The lower end of the sleeve formsy the seat r11 for theball-valve 8.' The ball-valve is soldered to the wire after the twooil-cham!1 V Y ber parts 1 and 2 are bolted together. The

pipe fitting 14 forms the oilinlet and is screwed o n after theball iswire.

With`thisconstruction, the oil level at thev burnerremains at exactlythe same place,

soldered to the u los regardless of Yhow much'thejoil chamber'` may be:tilted' in any'directioll, and centhe flame never varies, which is the,desideratum.

chamber is in its normal position and inl ball-valve 8 is operated atall times by both floats through the medium of the connectin l-bar ,7sustained and supported by these oats, and by adjusting the floats onltheir wires or rods 6 Athe position of the valve 8 with relation to thevalve-seat 11 maybe regulated. l

Thus it will be noticed that both the ballvalve and the needle-valve areat points below the burner, and in the form of the invention illustratedthe needle-valve is located betweeni the burner and the ball-valve, onevalve above, and the other below the oil- 'chamben vIn this way a simpleand most eiiicien means is provided for controlling the flow of oil inyoil-burning brooder-heaters, re-

gardless of any tilting of the oil chamber.

The oil level method of control might be employed when so desired-instead of the needle-valve by merely raising and lowering the burnerin relation to the oil chamber by any approved means. The foregoingtandem float in fact solves the problem of practical and safe oil levelflame control. The

4methods hitherto employed are dangerous because the entire heater mustbe set and kept level; in other words, a slight springing or warpingofthe floor will flood the burner.V v
